Real-time streaming of audiovisual content over the Internet is emerging as an important technology area in multimedia communications. Due to the wide variation of available bandwidth over Internet sessions, there is a need for scalable video coding methods and (corresponding) flexible streaming approaches that are capable of adapting to changing network(More)
Real-time streaming of audio-visual content over Internet Protocol (IP) based networks has enabled a wide range of multimedia applications. An Internet streaming solution has to provide real-time delivery and presentation of a continuous media content while compensating for the lack of Quality-of-Service (QoS) guarantees over the Internet. Due to the(More)
Psoriasis is an inflammatory skin disease with a multifactorial genetic basis. A recent genome-wide association study identified several psoriasis-predisposing loci, including IL-12B, which encodes the common p40 subunit of interleukin (IL)-12 and IL-23 and the IL-23 receptor gene (IL-23R). To investigate the relationships of these predisposing(More)
BACKGROUND Neutrophil/lymphocyte ratio (NLR) has been proposed as a novel marker of systemic inflammation and oxidative stress. The objective of this study was to ascertain the relationship between levels of NLR and recurrence of lone atrial fibrillation (AF) after catheter ablation. METHODS A total of 379 lone AF patients who underwent catheter ablation(More)
In this paper, we investigate the problem of MPEG-2 video quality degradation due to re-encoding using different coding parameters. We examined the statistical properties of pre-coded video and discovered tha t coding parameters can be recovered from pre-coded video because compressed video is represented by a limited set of parameters. We present an(More)
A panel of 52 murine monoclonal antibodies was found to recognize antigenic determinants that had been conserved among all major genetic subgroups of the H5N1 avian influenza virus prevalent since 1997. We screened a phage display library for peptides recognized by one such antibody (8H5). We analysed the specificity of 8H5 for reactive peptides presented(More)
We aimed to investigate the role of IL-12B gene polymorphism (rs6887695) in the disease susceptibility and clinical phenotypes of psoriasis vulgaris patients in the Chinese Han population. The genotype data of the IL-12B gene polymorphism (rs6887695) in 575 psoriasis patients and 1,403 normal controls were investigated using TaqMan technology. The(More)
